Polypropylene resin composition for oriented film and stretching film, comprises propylene polymer, which is obtained by polymerizing primary propylene containing monomers by forming crystalline propylene polymer component

摘要

The polypropylene resin composition comprises a propylene polymer, which is obtained by polymerizing primary propylene containing monomers by forming a crystalline propylene polymer component. The primary propylene containing monomers are further polymerized by forming another crystalline propylene polymer component. 1-10 wt.% of the former crystalline propylene polymer component is present in the propylene polymer. The crystalline propylene polymer components are produced by using titanium, magnesium and halogen containing catalyst.
